The aim of this study was to verify ovine health condition from
Uberlândia county (MG), searching the prevalence of the main infections
diseases that can reach ovine: leptospirosis, brucelosis (Brucella abortus and
Brucella ovis), maedi-visna, Chamydophila spp., neosporosis and
toxoplasmosis, associating these infections with risk factors. A total of 334
blood samples were collected randomly from both sex, different ages and
breeds from 12 farms in Uberlândia county. A epidemiologic questionary was
applied for each farm. The blood samples were submitted to Microscopic
Aglutination Test (leptospirosis) Buffered Brucella Antigen Test (brucelosis
Brucella abortus), Complement Fixation (Brucella ovis and Chlamydophila
spp.), Agar Gel Immunodifusion (maedi-visna) and Indirect Fluorescent
Antibody (neosporosis and toxoplasmosis) tests to search serology of these
infections. The prevalences were: 22.2% to leptospirosis and titers from 1/100
to 1/3200, 3.3% to Chlamydophila spp. and titers from 1/32 to 1/64, 8.1% to
neosporosis and titers from 1/50 to 1/3200 and 30.8% to toxoplasmosis. There
were not reactive ovine to brucelosis (Brucella abortus and Brucella ovis) and
maedi-visna. There was statistical significant difference (p<0.05) to reactive
ovine to leptospirosis: male, breed, beef sheep and with presence of rodents.
There was not statistical significant difference to brucelosis, maedi-visna,
Chlamydophila spp. and neosporosis with risk factors associated (p>0.05).
